Atezolizumab, bevacizumab, pemetrexed and platinum for EGFR-mutant NSCLC patients after EGFR TKI failure: A phase II study with immune cell profile analysis.
Trial report in Clinical and translational medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 11 papers, 1 of them a synthesis that pooled it.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundAcquired resistance to epidermal growth factor receptor tyrosine kinase inhibitors (EGFR TKIs) remains a significant hurdle for patients with EGFR-mutated non-small cell lung cancer (NSCLC), particularly those lacking the EGFR
methodsThis open-label, single-arm, phase II trial evaluated the efficacy and immune cell profile of the modified regimen combining atezolizumab, bevacizumab (7.5 mg/kg) and chemotherapy in patients with EGFR-mutated NSCLC following TKI failure. The primary endpoint was objective response rate (ORR). The re-biopsy tissue specimens and serial peripheral blood samples were collected to analyse the immune cell profile and tumour microenvironments. RRESULTS: 22 EGFR-mutant NSCLC patients participated in this study. The ORR was 42.9%, with a disease control rate (DCR) of 100%. Median progression-free survival (PFS) was 6.3 months. Patients with programmed death-ligand 1 (PD-L1) expression ≥1% exhibited significantly higher ORR (75 vs. 23.1%; p = .032) and longer PFS (14.0 vs. 6.1 months; p = .022) compared with those with PD-L1 expression < 1%. Grade ≥ 3 adverse events occurred in 40.9% of patients. Higher peritumour nature killer (NK) cell infiltration and lower peripheral helper T cell counts before treatment were associated with favourable ORR and longer PFS, respectively. After disease progression, the proportion of S100A9
conclusionThis modified combination regimen may be a promising therapeutic option for EGFR-mutant NSCLC patients with TKI resistance, especially those with PD-L1-positive tumours. Furthermore, immune cell profiling may aid in identifying patients who may benefit from this approach. KEY POINTS: The combination regimen yielded promising efficacy in NSCLC patients after EGFR-TKI resistance, particularly those with PD-L1-positive tumours. Higher peritumour NK cell and lower peripheral helper T cell were associated with favourable ORR and longer PFS, respectively. After disease progression, the proportion of S100A9
